    "title": "Differential Measurements of an AC Source with a Josephson Arbitrary Waveform Synthesizer",
    "description": "The abstract of the paper [1] is:This paper describes differential sampling measurements of an ac source and a Josephson arbitrary waveform synthesizer (JAWS).A new iterative approach for aligning the phases of the JAWS and the source waveforms was implemented to minimize the differential voltage at the digitizer. A type-A uncertainty of 45 nV\/V after 10 min was measured for a commercial ac source at 1 V rms amplitude and 1 kHz.[1] \"Differential Measurements of an AC Source with a Josephson Arbitrary Waveform Synthesizer\"submitted to Conference on Precision Electromagnetic Measurements (CPEM) 2024; will be published and available on IEEE website at a later date.Data for figures 2 to 4 of the manuscript.Files included in this publication:   Fig 2 FFT of the digitizer signal.csv    Figure 2    Fig. 2. 1 kHz component of the FFT of the digitizer signal (amplitude and phase) for Delta_V1=Source-JAWS1 and Delta_V2=Source-JAWS2 over 3.5 hours    Five columns: The first column is the time (x-axis), the second column is the amplitude in volt of the first measured difference voltage (shown as black solid circle in Fig. 2),     the third column is the phase in degree of the first measured difference voltage (shown as black open circle in Fig. 2),    the fourth column is the amplitude in volt of the second measured difference voltage (shown as red solid circle in Fig. 2),    the fifth column is the phase in degree of the second measured difference voltage (shown as red open circle in Fig. 2).    Format: CSV  Fig 3 Source rms amplitude and environment data.csv    Figure 3    Fig. 3. Room environment conditions recorded (temperature, atmospheric pressure, and relative humidity) and Reconstructed rms amplitude for the source at 1 kHz.    Five columns: The first column is the time (x-axis), the second column is the reconstructed amplitude in volt - 1 V (shown as blue solid circle in Fig. 3 bottom),     the third column is the temperature in degree C (shown as orange solid square in Fig. 3 top),    the fourth column is the atomsepheric pressure in hecto Pascal  (shown as green open triangle in Fig. 3 top),    the fifth column is the relative humidity in percent (shown as puple open circle in Fig. 2).    Format: CSV  Fig 4 Allan variance.csv    Figure 4    Fig. 4. Allan deviation of the source amplitude measured at 1 V and 1 kHz.    Five columns: The first column is the time (x-axis), the second column is the calculated Allan Deviation in volt (shown as blue solid circle in Fig. 4),     the third column is the fit on the results, representing the white noise with slope -0.5 (shown as black dash line in Fig. 4),    the fourth column is the is the time (x-axis) for the 1\/f noise floor plot and the fifth column is the 1\/f noise floor (shown as a black solid line in Fig. 4)    Format: CSV",
